a four - year field experiment (1999-2002) was conducted on a silty clay loam soil at laklak research field of hamedan to determine the effects of crop residue management and plowing depth on soil fertility and wheat yield in a maize-wheat rotation. in this investigation, four corn residue managements were used consisting of 1) stalk shredding by maize stalk shredder 2) stalk shredding by disk ...

the quality control of microbial contamination in meats consumed in restaurants of university of tehran was taken into consideration. for this reason, 100 sterile samples were taken from 4 central restaurants, from may until october 1995, the samples were as follows: 12 samples of meat, 50 samples of chopped meat and 38 samples of minced meat. all of the samples were examined to search for meso...

The effect of pelleting fodder on voluntary feed intake and digestibility in sheep was tested with sorghum straw cowpea haulm two forms (chopped granulated). Twenty-four (24) sheep, 18 to 24 months old, Djallonké breed were divided into 4 groups 6 following a random complete block device four (04) treatments as follows: R1= 50% chopped + haulms, R2 = Granulated 1 (50% haulms), R3 maize bran R4 ...

The anaphylactic release of histamine from perfused, chopped guinea pig lung is very sensitive to changes in the NaCl concentration of the containing medium, and it is ionic strength rather than particle concentration which is critical. Consequently, in studies with inhibitors care must be taken to avoid inadvertently increasing ionic strength and thereby misinterpreting the cause of the inhibi...

We make some progresses on Saxl Conjecture. Firstly, we show that the probability a partition is comparable in dominance order to staircase tends zero as grows. Secondly, for partitions whose Durfee size k where k?3, by semigroup property, there exists number nk such if tensor squares of first contain all irreducible representations corresponding with k, then k. Especially, n3=14 and n4=28. Fur...

In ground based infrared imaging a well-known technique to reduce the influence of thermal and background noise is chopping and nodding, where four different signals of the same object are recorded from which the object is reconstructed numerically. Since noise in the data can severely affect the reconstruction, regularization algorithms have to be implemented. In this paper we propose to combi...
